In 2003 Mitered Drain (patent pending) was developed by a civil engineer to provide an innovative cost effective alternative to conventional drop inlets and catch basins. Mitered Drain can be connected directly to the end of the pipe. This allows for increased swale lengths longer surface flow and greater biotreatment and groundwater infiltration. Mitered Drain facilitates compliance with new environmental design regulations regarding storm water runoff and the Clean Water Act.

Mitered Drain is perfect for use in hard to drain areas where lack of grade difference is a problem. Because of its sloped grate water flows directly into the pipe eliminating the drop typical in conventional inlets allowing for better drainage in flat areas that need extra slope to achieve proper drainage.
